I'm on a pool right now and it's taking forever to update the confirmed/unconfirmed balance - like for the past 1-2 hours

anyone else experiencing this?

The 2 slot. This one - http://www.newegg.com/Product/Product.aspx?Item=N82E16814121803

No sir! Just stock bamt 1.1 and 1.3 instances (well stock until i messed them up for vertminer). Figure i should mention my 2 other Powercolor 7950's in my bamt 1m3 system are getting 312.9 and  313.3 respectively.

which model do you have? the 3 slot version or the 2 slot? (the 3 slot is v2, the non v2 version is the 2 slot one)

I have the 3 slot one and can get nowhere near that, lucky with 280/300

This is getting me an average of 344kh/s with an ASUS R9 280X.

Hi,

this is the config for my AMD Sapphire r9 290 (Hawaii, firmware updated)  under debian jessie and catalyst 14.1


export GPU_MAX_ALLOC_PERCENT=200
export GPU_USE_SYNC_OBJECTS=1



{
"pools" : [
  ....
],
"intensity": "20",
"worksize": "256",
"vectors" : "1",
"lookup-gap" : "2",
"gpu-fan" : "100",
"thread-concurrency": "33280",
"gpu-engine": "1000",
"gpu-memclock": "1500",
"gpu-powertune" : "20",
"temp-cutoff" : "120",
"temp-overheat" : "80",
"temp-target" : "70",
"api-port" : "4028",
"expiry" : "120",
"gpu-threads" : "1",
"log" : "5",
"queue" : "0",
"scan-time" : "60"
}


The result is 391 kh/s with ZERO HW

What are your settings?

Anyone got any ideas on why my reject rate is so high (about 30%)
no hw errors, and barely hashing 300 kh/s on one rig (3 r9 280x asus)
the 2nd one has the exact same cards, mobo, and memory as the first, but the best it can do is about 250 kh/s per card.. the only diff is the first pc has a phenom x3 and the 2nd one has a semperon 145..

I'm using i13, tc8250 g1 lookup gap 0 or 2 (doesn't matter to hash rate) and g1 (using 2 makes my 3rd vid card crash)

Anyone have an advice on how to set parameters for cpuminer on i7 4770k ?

Been trying to tweak for my 7990 (2x7970 with 3GB VRAM per GPU), and I can't get more than 470-480 KH/s which is only a third of what I get with normal cgminer/kalroth.

I'm using --intensity 13 --lookup-gap 2 -g 2 -w 184 --shaders 2048 --thread-concurrency 6112

This is the maximum intensity, work memory and TC I can reach without hw-errors. Anyone made better results with 7970/7990?

502 Bad Gateway

nginx
why does it do this often when I try to change pages,

but whatever,

Still can't get 7950 HD to get past 8-10Khs, have posted link above but quote took my post also, with link I have and problem trying to dl that program. If I can actually download it with some help, can I run it like cgminer suchas just from cmd. I have never got a config or batch file to work ever so I just enter my perrimeters in start run cmd on windows and it works fine without a bat or config, but on vertigo, can't get past the 8-10khash. plz help saphire raydon sku 11196-20-19g

Using Bamt, the first line for that "hack" that you enter copies vertminer from the net to your usb stick.

I'm a bit surprised by the 7950 results I have been seeing in this thread. I modified almost nothing from my config from when i was mining scrypt, and I fired up vertminer in a modified bamt 1.1 setting (using this mod https://bitcointalksearch.org/topic/m.4668635) and here is what I get:

Powercolor 7950 PCS+ - 314.5 kh/s
core/mem 1070/1500,
stock vddc,
thread-concurrency of 21712,
gpu-threads 1,
lookup-gap 1
intensity 20,
worksize 256
temperature is 74C at 59% fan (set to auto)

XFX 7950 DD (TDKC) - 307.7 kh/s
core/mem 1040/1495,
stock vddc,
thread-concurrency of 21712
gpu-threads 1,
lookup-gap 1
intensity 20,
worksize 256
temperature is 73C at 86% fan (set to auto)

No HW errors and a 0.4% reject rate.


I also have a 5770 in the same system running at 83.1 kh/s
core/mem 910/1250,
vddc 1.100,
thread-concurrency of 3100,
gpu-threads 1,
lookup-gap 1
intensity 18,
worksize 256
temperature is 67C (fan not registering a speed apparently. might be too low)


This is all running on a very old system that consists of a DFI NF4 Ultra-D with a single core Opteron 146 CPU and 1GB DDR. I see no correlation between amount of system memory and thread-concurrency settings. My other system runs with 4GB of DDR2 and the results i get for my 7950's in scrypt are the same.

I was starting to wonder if I could go higher by changing my TC, but from what I see, i'm probably pushing the limit already.

I have another rig running 2 more 7950's and a 270x on bamt 1.3. If I have time, I will modify my bamt 1.3 for vertminer and see how it performs.

EDIT: ASUS DirectCU II TOP R9 270X in BAMT 1.3 - 191 kh/s
core/mem 1100/1250,
vddc stock,
thread-concurrency of 12288,
gpu-threads 1,
lookup-gap 1
intensity 19,
worksize 256

--gpu-platform 0 -I 19-w 256 --thread-concurrency 16384  --gpu-engine 1070 --gpu-memclock 1500

8-10Khash/sec same with other 7950 HD posted what gives also using modified cg that vertigo said to use

Also whats up with this 502 Bad GatewayShit, been trying to post for 30 min already?"

Hi,

Can anyone explain the need for more system memory with the new vertminer?  
Is there a formula we can use to determine if adding memory will help with the kh's?  
I'm running vertminer and have 3gb's free, is the additional memory requirement just a measure of total memory in the system and not used?
Randomly people are adding in memory and getting better results, it would be great if someone that added memory
into their system posted a measurement of ram used before and after adding it, or someone knowledgeable on the new
algorithm posts an explanation.

Dave

have same card, can't get more than 8-10 K what am I doing wrong, using underclocking, can usually get 630Khash with normal script
